LP PHY Dell device not working properly with b43 even in PIO mode

LP PHY Dell device not working properly with b43 even in PIO mode

[Anisse Astier]

Hi,

Running John Linville's wireless-next tree(HEAD:
6d1d4ea4a82f8c17a3ff7c2f677bc3d41ea7484b), I have troubles with a
Broadcom wireless card that can't properly connect. This device is also
managed by wl, that supports it more or less properly (at least without
crashing). AFAIK, the card isn't supported by brcm80211.

It can connect, and even get an IP, but after some time it will just stop
working until reboot. The AP uses WPA2-PSK/TKIP.


The device:
0e:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
	Subsystem: Dell Wireless 1397 WLAN Mini-Card [1028:000c]

The log (I have similar problems if I load it directly in PIO mode) :

On some boxes, 14e4:4315 devices fail in b43 with with this DMA error. We don't
know why, nor do we know how to fix it. Unfortunately, none of the developers
have such a system, which makes the debugging harder.

I don't think the problem is with the Dell 1397, but with the motherboard on the
laptop. In fact, most of the problems have been with netbook computers with a
Phoenix BIOS. Does your system fit that description?

Are the MAC suspend failures in PIO mode a regression that recently appeared? I
cannot think of any changes that should have affected the LP PHY devices, but
anything is possible.

The only workaround I can suggest is to use wl. I hate to recommend
closed-source software, but there may be no alternative.
